Abstract
The utility model discloses a variable buoyancy automatic liquid level recording instrument which comprises a base, a barrel body, a water inlet pipe, a data collector, a sensing bar and a gravity sensor, wherein the sensing bar is placed in the barrel body vertically, and a signal input end of the data collector is communicated with a signal output end of the gravity sensor. Compared with the existing water level measuring instrument, the recording instrument is low in cost, stable in structure, easy and practical, and wide in application range, can record timely, and can realize remote control.
Description
Technical field
The utility model relates to a kind of level measuring instrument, relates in particular to a kind of floating type liquid level self-recording device.
Background technology
Present liquid level test is every field such as utilization water conservancy, agricultural, ecology and life extensively, according to test liquid type and precision prescribed, corresponding sensor is all different, the method of test is more, the more mareograph of utilization on the hydrology, by the growth and decline of ball float lifting signal record water level, manually irregularly change paper (diary type, journal formula) but must be aided with, also have defectives such as steel wire easily comes off; Condenser type, resistance-type test result are subject to medium composition and temperature effect; Methods such as radar, ultrasound wave, radiant type, must be furnished with the exclusive data gatherer, the singularity of sensor causes the cost cost higher in addition.
The utility model content
At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of application law of buoyancy, and existing general sensing and data collector are carried out composite design, has solved above problem, the liquid level self-recording device that the liquid water level is monitored.
The technical solution of the utility model is: a kind of change floating type liquid level self-recording device, comprise base, cylindrical shell and water inlet pipe, also comprise data collector, inductive rod and gravity sensor, described inductive rod vertically is positioned over inner barrel, and described data collector signal input part is communicated with the signal output part of gravity sensor.
As preferably: described base and cylindrical shell are one-body molded.
As preferably: described gravity sensor signal adopts is convenient to the general resistance signal that data collector receives.
As preferably: described inductive rod and gravity sensor removably connect.
As preferably: described water inlet pipe is provided with flowrate control valve.
The beneficial effects of the utility model are: the utility model cost is low, and Stability Analysis of Structures is simple and practical, and is applied widely, but real time record and remote monitoring, and measuring accuracy is not influenced by temperature, medium composition etc., has kept result's stability and comparability; Measuring accuracy and liquid level change scope, precision, the load of size, length and sensor that can be by selecting inductive rod for use have made up, have realized the diversity of product; The signal of described gravity sensor adopts general resistance signal, is suitable for big extremely data collector, has realized like this and the public property of other monitoring target, needn't purchase the exclusive data gatherer, and then also reduce cost of products.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1. cylindrical shell; 2. base; 3. water inlet pipe; 4. inductive rod; 5. gravity sensor; 6. data collector; 7. flowrate control valve.
Embodiment
Embodiment: as a kind of embodiment of the present utility model, as shown in Figure 1, a kind of change floating type liquid level self-recording device, comprise base 2, cylindrical shell 1 and water inlet pipe 3, described base 2 and cylindrical shell 1 are one-body molded, structure firmly is difficult for collapsing, convenient layout in the open air, described water inlet pipe 3 is provided with flowrate control valve 7, make things convenient for Control Flow, its water inlet pipe 3 can be communicated with the cistern on the engineering and carries out water yield collection, also can be with inductive rod 4, the combiner that gravity sensor 5 and data collector 6 constitute places liquid level top directly to monitor, the scope of application is wider, also comprise data collector 6, inductive rod 4 and gravity sensor 5, described inductive rod 4 vertically is positioned over cylindrical shell 1 inside, described data collector 6 signal input parts are communicated with the signal output part of gravity sensor 5, but real time record and remote monitoring, measuring accuracy is not subjected to temperature, influences such as medium composition, the stability and the comparability that have kept the result, described gravity sensor 5 signals adopt is convenient to the general resistance signal that data collector 6 receives, described inductive rod 4 removably connects with gravity sensor 5, measuring accuracy and liquid level change scope can be by selecting the size of inductive rod 4 for use, the precision of length and gravity sensor 5, load makes up, realized the diversity of product.
